What kind of grass resists erosion better? I chose this experiment because erosion is a big problem and I wanted to find some ways to protect against erosion. My hypothesis is that there will not be a measurable difference in what kind of grass resists erosion better. I guessed this because my neighbors use different kinds of grass and their soil is all the same height. First, put the dirt in sectioned tray. Next, plant each seed in one of three sections of the tray. Then, put the tray under the light. Then, water twice a day. Next, let grass grow until grass is about 6-8cm. Then, put tray at an angle. Next, spray evenly with hose. Then, measure how much soil has washed away. Lastly, record results. My
conclusion is that Ryegrass resists erosion the best. I got this result
because it grew the thickest and laid down to form a mat to protect the
soil from the water. This information can be used in the world to help
prevent erosion in peoplesí yards. If they have an area that is prone to
having the soil wash off, they can choose to plant a grass like Ryegrass
that provides a good cover.
